Other points of interest[edit]


  1. In the damaging moat area at the north end of the map, press on the recessed wall at the back end to find a cave containing a box of rockets, a megaarmor, and a backpack. (sector 21)
  2. In the southeast room with the crusher and the red key teleporter, after you receive the red key, head north from the crusher down the steps and use the red bars, then enter the portal. Use the red bars to the north and backtrack to the previous set of red bars, then go through it again, where you will not teleport this time. Instead you will jump into the large well inside the room. Go to the southeast corner to teleport to a side room in the spider mastermind room, where you will find armor bonuses, a radiation suit, a medikit, and a stimpack. (sector 117)
  3. In the caves at the northeast end of the map, take the silver lift up to a supply room and use the brown wall to find a radiation suit. (sector 151)
